- Abstract
Several novel chiral bifunctional L-thiazoline-thiourea derivatives were easily synthesized from commercially available L-cysteine in high yield. These catalysts were subsequently applied to the of acetylacetone to β-nitrostyrenes. The products with S configuration were obtained in 98% enantiomeric excess ( ee) when the L-thiazoline-thiourea derivatives were used. A plausible transition state model is proposed to explain the observed . Chirality 27:979-988, 2015. © 2015 Wiley Periodicals, Inc.
